# Industrial Specification: Head Section

## 1. Technical Definition
The discharge end of an elevator bucket conveyor where materials are transferred out of the buckets.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s linear velocity, 15-45 RPM rotational speed, 0.1-0.8 MPa bearing pressure**. Failure boundary: **Material discharge velocity exceeding 4.2 m/s causes centrifugal throw beyond collection chute, bearing temperature exceeding 120°C initiates lubricant breakdown**, Mechanism: **Centrifugal force exceeding material adhesion threshold (F_c &gt; μ·m·g) causes overshoot; Boundary layer lubrication failure at Sommerfeld number &lt;0.001 causes bearing seizure**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Material buildup exceeding 15mm thickness on discharge chute surfaces | 8 | Increased friction coefficient from 0.25 to 0.45 causing belt slippage of 8-12% | Install 316L stainless steel wear plates with 45° chamfer edges and automated pneumatic vibrators at 50Hz frequency |
| Shaft misalignment exceeding 0.15mm/meter over 2-meter span | 8 | Bearing load concentration exceeding 2.5× design rating causing L10 life reduction from 20,000 to 3,000 hours | Implement laser-aligned pillow block bearings with 0.02mm precision and torque-limiting couplings rated at 350 N·m |
